Why the study?
Does propranolol alter myocardial blood flow and oxygen balance during exercise in conscious dogs?
Does propranolol alter myocardial blood flow and oxygen balance during exercise in conscious dogs?
Beta-blockade with propranolol alters the myocardial oxygen supply-demand relationship during exercise, leading to higher oxygen extraction for a given level of oxygen consumption.
May heighten myocardial oxygen extraction during exercise in dogs; leaves open human translation.
